Eccentrically Cycloidal Drive Model

thingiverse

Most modern gearing mechanisms have been invented decades or even centuries ago, but not so with the Eccentrically Cycloidal (EC) drive. In fact, its patents are still pending, and the ink is barely dry on them! This 3D-printable model is made available to the public by the patent holder, who has given explicit permission for it to be shared. The EC drive looks like something straight out of a science fiction movie, but it's surprisingly efficient and extremely compact. Its gear ratio of 1:9 is an almost impossible feat to achieve with standard involute gears. For more information on EC gears, check out http://www.ec-gearing.com or watch the video at https://youtu.be/PzTXB7pUj6w. Here are the print settings I used: Printer Brand: MakerGear Printer: MakerGear M2 Rafts: No Supports: No After printing, you'll need to assemble the hardware. Here's what you'll need: * 4 Metric countersunk Phillips-head M3x12 screws * 2 Metric M3 nuts Assembly is a breeze! Simply secure the washer and spinner with screws, then connect leg1 and leg2 to the stand using two screws and nuts. You can also cap the legs with a bridge on top (just like in the video).
